Abstract

The rim (3) has an outer rim (3.1), two rim flanges (3.2), multiple spokes (3.3) and a rim hub (3.4) that are connected to a vehicle hub by bolts (4) and nuts. The spokes are connected with the rim hub and the outer rim or the rim flanges. A pyrotechnic element (6) is releasably arranged in the spokes for separating the spokes. The rim flanges deform locally when exposed to a defined force. The rim is integrally formed by casting and/or forging. The pyrotechnic element is triggered by a security device e.g. airbag, of a vehicle (1) upon detection of a front crash. An independent claim is also included for a vehicle comprising a security device.

Description

Die Erfindung betrifft eine Felge für ein Fahrzeug gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a rim for a vehicle according to the preamble of claim 1.

Bekannte Sicherheitssysteme an Kraftfahrzeugen umfassen Mittel zur Detektion eines Frontalaufpralls und davon abhängig auslösbare Airbags und/oder Gurtstraffer, um Fahrzeuginsassen vor beim Aufprall wirkenden Kräften zu schützen. Die Kraftfahrzeuge sind zudem so ausgebildet, dass Aufprallenergie gezielt durch Deformation von Fahrzeugteilen abgebaut wird, um eine Deformation einer Fahrgastzelle gering zu halten.Known safety systems on motor vehicles include means for detecting a frontal impact and dependent thereon releasable airbags and / or belt tensioners to protect vehicle occupants against impact forces. The motor vehicles are also designed so that impact energy is selectively reduced by deformation of vehicle parts to keep a deformation of a passenger compartment low.

Ebenso ist bekannt, Felgen des Fahrzeugs mit einem Deformationsbereich zwischen einem Felgenhorn und Speichen auszubilden, der sich abhängig von einer auf die Felge einwirkenden Kraft verformt, um Aufprallenergie abzubauen. Insbesondere verformt sich dabei das Felgenhorn.It is also known to form rims of the vehicle with a deformation range between a rim flange and spokes, which deforms depending on a force acting on the rim force to reduce impact energy. In particular, this deforms the rim flange.

Es ist eine Aufgabe der vorliegenden Erfindung, eine verbesserte Felge für ein Fahrzeug anzugeben.It is an object of the present invention to provide an improved rim for a vehicle.

Die Aufgabe wird erfindungsgemäß gelöst durch eine Felge mit den Merkmalen des Anspruchs 1.The object is achieved by a rim with the features of claim 1.

Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.Advantageous developments are the subject of the dependent claims.

Eine erfindungsgemäße Felge für ein Fahrzeug umfasst ein Felgenbett, zwei Felgenhörner, eine Mehrzahl von Speichen und eine Felgennabe, die mit einer Fahrzeugnabe verbindbar ist, wobei die Speichen einerseits mit der Felgennabe und andererseits mit dem Felgenbett oder einem der Felgenhörner verbunden sind.A rim for a vehicle according to the invention comprises a rim well, two rim flanges, a plurality of spokes and a rim hub connectable to a vehicle hub, the spokes being connected to the rim hub on the one hand and to the rim base or one of the rim flanges on the other hand.

Erfindungsgemäß ist in oder an mindestens einer der Speichen ein pyrotechnisches Element angeordnet, mittels dessen die Speiche schwachbar oder durchtrennbar ist. Somit lässt sich die betreffende Speiche, insbesondere in einem Übergang zum Felgenhorn geometrisch so schwächen, dass ein zusätzlicher Deformationsweg entsteht, mittels dessen Aufprallenergie abgebaut wird. Auf diese Weise wird eine Belastung von Fahrzeuginsassen durch die Aufprallenergie reduziert. Gleichzeitig verbessert sich die gestalterische Freiheit beim Design der Felge. Beispielsweise können die Speichen bis zum Felgenhorn durchgezogen werden.According to the invention, a pyrotechnic element is arranged in or on at least one of the spokes, by means of which the spoke is weak or severable. Thus, the spoke in question can weaken geometrically, in particular in a transition to the rim flange, so that an additional deformation path is created by means of which impact energy is dissipated. In this way, a load of vehicle occupants is reduced by the impact energy. At the same time, the design freedom in the design of the rim improves. For example, the spokes can be pulled through to the rim flange.

Im Folgenden werden Ausführungsbeispiele der Erfindung anhand einer Zeichnung erläutert.In the following, embodiments of the invention will be explained with reference to a drawing.

Dabei zeigt:Showing:

1 eine Felge an einem Fahrzeug bei oder nach einem Frontalaufprall. 1 a rim on a vehicle during or after a frontal impact.

In 1 ist ein Teil eines Fahrzeugs 1 mit einem Rad 2 gezeigt, das infolge eines Frontalaufpralls und definierter Deformation von Fahrzeugteilen aus einer Normalstellung am Fahrzeug 1 entgegen einer Fahrtrichtung F, das heißt nach hinten verschoben ist. Das Rad 2 umfasst eine Felge 3 mit einem Felgenbett 3.1, zwei Felgenhörner, von denen nur das äußere Felgenhorn 3.2 dargestellt ist, eine Mehrzahl von Speichen 3.3 und eine Felgennabe 3.4, die beispielsweise mittels Radschrauben 4 oder Radmuttern (nicht dargestellt) mit einer Fahrzeugnabe (nicht dargestellt) verbunden ist. Die Speichen 3.3 sind einerseits mit der Felgennabe 3.4 und andererseits mit dem Felgenbett 3.1 oder einem der Felgenhörner, insbesondere dem äußeren Felgenhorn 3.2 verbunden. Auf der Felge 3 ist ein Reifen 5 angeordnet.In 1 is a part of a vehicle 1 with a wheel 2 shown as a result of a frontal collision and defined deformation of vehicle parts from a normal position on the vehicle 1 against a direction of travel F, that is shifted to the rear. The wheel 2 includes a rim 3 with a rim base 3.1 , two rim flanges, of which only the outer rim flange 3.2 is shown, a plurality of spokes 3.3 and a rim hub 3.4 , for example, by means of wheel bolts 4 or wheel nuts (not shown) to a vehicle hub (not shown) is connected. The spokes 3.3 are on the one hand with the rim hub 3.4 and on the other hand with the rim base 3.1 or one of the rim flanges, in particular the outer rim flange 3.2 connected. On the rim 3 is a tire 5 arranged.

In oder an mindestens einer der Speichen 3.3, vorzugsweise an einer Mehrzahl oder jeder der Speichen 3.3 ist ein pyrotechnisches Element 6 angeordnet, mittels dessen die jeweilige Speiche 3.3 schwächbar oder durchtrennbar ist.In or on at least one of the spokes 3.3 , preferably at a plurality or each of the spokes 3.3 is a pyrotechnic element 6 arranged, by means of which the respective spoke 3.3 weakenable or severable.

Das pyrotechnische Element 6 kann fernauslösbar ausgebildet sein.The pyrotechnic element 6 can be designed remotely triggered.

Die Felgenhörner 3.2 können definiert so ausgebildet sein, dass sie sich lokal bei Einwirken einer definierten Kraft deformieren.The rim flanges 3.2 can be defined so that they deform locally under the action of a defined force.

Die Felge 3 kann ein- oder mehrstückig ausgebildet sein, insbesondere als eine Leichtmetallfelge, umfassend Aluminium und/oder Magnesium.The rim 3 may be formed in one or more pieces, in particular as a light metal rim, comprising aluminum and / or magnesium.

Die Felge 3 kann durch Gießen und/oder Schmieden gebildet sein.The rim 3 may be formed by casting and / or forging.

Die Fernauslösung eines oder mehrerer der pyrotechnischen Elemente 6 kann mittels einer Sicherheitsvorrichtung erfolgen, die Mittel zur Detektion eines Frontalaufpralls umfasst, beispielsweise im Bereich eines Stoßfängers angeordnete Sensoren. Bei Detektion eines Frontalaufpralls, insbesondere bei Überschreitung einer definierten Aufprallenergie, kann die Sicherheitsvorrichtung die pyrotechnischen Elemente 6 gezielt auslösen, um die Speichen 3 zu schwächen oder zu durchtrennen, und einen Deformationsweg zu verbessern.The remote release of one or more of the pyrotechnic elements 6 can be done by means of a safety device comprising means for detecting a frontal impact, for example, arranged in the region of a bumper sensors. Upon detection of a frontal impact, in particular when exceeding a defined impact energy, the safety device, the pyrotechnic elements 6 specifically trigger the spokes 3 to weaken or sever, and to improve a deformation path.
